Managing packet data interconnections in mobile communications
First Claim
1. A method for use in managing data interconnections in a mobile communications network having multiple packet control function entities (PCFs) and multiple packet data serving nodes (PDSNs), wherein each PCF and PDSN communicates signaling messages according to a mobile signaling protocol, the method comprising:
- receiving information for a Mobile Subscriber (MS); and
associating the MS with a same one of the PDSNs when the MS moves from a first area covered by a first PCF to a second area covered by a second PCF.

Abstract
Data interconnections are managed in a mobile communications network having multiple packet control function entities (PCFs) and multiple packet data serving nodes (PDSNs), wherein each PCF and PDSN communicates signaling messages according to a mobile signaling protocol. Information for a Mobile Subscriber (MS) is received. The MS is associated with a same one of the PDSNs when the MS moves from a first area covered by a first PCF to a second area covered by a second PCF. It is determined that a first PCF has issued a first connection request on behalf of an MS. As a result of the first connection request, a selection protocol is executed a first time to select a PDSN that corresponds to the MS. It is determined that a second PCF has issued a second connection request on behalf of the MS. The selection protocol is executed a second time to select the same PDSN that was selected as a result of the first connection request.

10. A method for use in managing packet data interconnections in a mobile communications network having multiple packet control function entities (PCFs) and multiple packet data serving nodes (PDSNs), wherein each PCF and PDSN communicates signaling messages according to a mobile signaling protocol, the method comprising:
-
maintaining a list of the PDSNs;
executing a hashing protocol to map a number derived from an MS identification number onto the list of PDSNs;
deriving a result from the mapping; and
including the result in a response to a connection request from one of the PCFs.

11. A method for use in managing packet data interconnections in a mobile communications network having multiple packet control function entities (PCFs) and multiple packet data serving nodes (PDSNs), wherein each PCF and PDSN communicates signaling messages according to a mobile signaling protocol, the method comprising:
-
determining that a first PCF has issued a first connection request on behalf of a Mobile Subscriber (MS); and
by an entity other than one of the PCFs or one of the PDSNs, determining whether to execute a selection protocol to select, from among the PDSNs, a PDSN that corresponds to the MS.

12. A method for use in managing packet data interconnections in a mobile communications network having multiple packet control function entities (PCFs) and multiple packet data serving nodes (PDSNs), wherein each PCF and PDSN communicates signaling messages according to a mobile signaling protocol, the method comprising:
-
determining that a PCF has issued a connection request on behalf of a Mobile Subscriber (MS); and
causing a response to be issued back to the PCF directing the PCF to issue a connection request to a service address of one of the PDSNs, the one of the PDSNs also having a redirection address. - View Dependent Claims (13, 14, 15)
